VIX tier allocation

A rules-based strategy that shifts from cash toward stocks and leveraged ETFs as the VIX rises, with its five tiers, rebalancing rules and risks.

Education only, not advice. Leveraged and strategy-driven investing can lose most of its value quickly. Figures are historical or backtested and do not predict future results.

The idea

The The VIX (volatility index) rises when investors are afraid, and fear tends to peak near market bottoms. This strategy turns that into a rule: hold more cash when the VIX is low and people are calm, and deploy more into stocks, and a small amount of leverage, as the VIX rises.

The five tiers

Tier boundaries use "less than", so a VIX of exactly 15 falls in the second tier.

VIX BIL (cash) SPY QQQ TQQQ (3x) Fear level
Under 15 25% 50% 20% 5% Low, complacency
15 to 25 20% 40% 30% 10% Moderate
25 to 35 15% 35% 35% 15% Elevated
35 to 45 10% 30% 40% 20% High
45 and up 5% 20% 50% 25% Extreme, crisis

Rules

  1. Check the VIX close.
  2. Rebalance on the first trading day of each month, or at once if the VIX moves into a new tier.
  3. Never hold more than 25% in TQQQ. That cap is the most important risk control.
  4. Commit to at least 10 years.

Why it might work

It buys more when prices are low and fear is high, and trims when markets are calm. It is a form of Mean reversion applied to fear, not a forecast.

Risks

  • Leverage. TQQQ fell about 80% in 2022 and more than 70% in early 2020. See Volatility decay.
  • Bear markets can last. A high VIX can persist for months while prices keep falling, so the extra risk is added into a falling market.
  • Cash drag in long calm bull markets.
  • Concentration in large US technology through QQQ and TQQQ.
  • Discipline. The rule only works if you follow it when it feels worst.
